Things that sound dirty

There I was, pondering the question "Was Flogging Molly a euphemism before it was a band name?" After a quick search, I was sidetracked by this thread:

One choice offering was the wikipedia page for a mineral:

I was dubious as to the authenticity of the wiki entry, but a further search suggests it is an actual mineral.

Anyone have any other things that sound dirty but [probably, usually] are not?

It's kind of dumb, but the chicks are cute.
